tested above the limit and provide the stack test report or results within one hundred and

twenty (120) days after the date of the test that failed to demonstrate compliance. If this

subsequent test shows compliance, the prior exceedance will not be considered a violation of

this Consent Judgment and compliance testing will return to a schedule consistent with the

Secondary Lead MACT, revised as ofJanuary 5, 2012.

9. Monitoring

A. Missouri has a lead monitoring site network, the 2011 Missouri Ambient Air

QuaJity Monitoring Network Plan, which was approved by EPA on December 12, 2011.

MDNR will monitor consistent with the Monitoring Plan and any amendments thereto. Data

from any MDNR, BRRF or Doe Run monitor that is not located within ambient air will be

used solely for informational purposes and not for determining attainment with the 2008

LeadNAAQS.

B. BRRF has two non-ambient monitors at the sites known as the North and South

BRRF monitoring sites. BRRF shall continue data collection from these monitors until data

collected from the ambient air network for 36 three-month rolling averages shows continuous

attainment with the 2008 Lead NAAQS, until BRRF or Doe Run no longer owns or operates

the property where the monitors are located, or upon approval by MDNR that continued

monitoring is not necessary.

C. BRRF has a meteorological station and shall continue to monitor meteorological

data to support future dispersion modeling or other episode analysis. Meteorological data

8 collection shall include ten (10) meter wind speed, ten (10) meter wind direction, ten (10)

meter ambient temperature, ambient barometric pressure, ten (10) meter sigma theta, ten (10)

meter delta temperature, relative humidity, and precipitation. Meteorological data will also

include two (2) meter ambient and delta temperature and incoming solar radiation within six

(6) months after the effective date. Doe Run shall continue data collection from these monitors until data collected from the ambient air network for thirty-six (36) three-month rolling averages shows continuous attainment with the 2008 Lead NAAQS, until BRRF or

Doe Run no longer owns or operates the property, or upon approval by MDNR that the continued monitoring is not necessary.

D. Meteorological monitoring shall be conducted pursuant to an MDNR-approved

Quality Assurance Project Plan ("QAPP"). BRRF shall submit the QAPP to MDNR for review and approval within sixty (60) days ofentry ofthis Consent Judgment.

E. BRRF shall provide to MDNR the air monitoring data analysis within thirty (30) days after the end ofeach calendar month.

F. BRRF shall provide to MDNR the meteorological monitoring data and quality assurance summaries in a quarterly report within forty-five (45) days after the end of each calendar quarter electronically in the format identified in the QAPP.

G. If BRRF or Doe Run purchases property where the MDNR Buick North East monitor is located, Doe Run or BRRF shall allow MDNR access to the property for the purposes ofcontinuing the 2008 Lead NAAQS monitoring.

H. BRRF and Doe Run shall notify MDNR of any real property acquired or released from its possession in the BuicklVibumum trend nonattainment area where an MDNR monitor is located or within where a BRRF fenceline to preclude public access is located

9 within thirty (30) days of the transaction being filed with the local Recorder of Deeds. This

notification shall include a copy of the Warranty Deed and legal description of the property.

10. Projects Required as Contingency Control Measures

A. If the air quality data for any three-month rolling average period exceeds the 0.15

J,.1g/m3 three-month rolling average lead standard after completion and operation of projects

and control measures identified in paragraph 6, or any extension date granted by the MDNR,

BRRF shall begin implementation of these contingency measures upon written notification

from MDNR, and shall complete the projects according to the following schedule. The

triggering period for purposes of this provision will be the three-month calendar period

following the implementation of the projects and control measures identified in paragraph 6.

Additionally, if BRRF fai1s to make Reasonable Further Progress (defined as the completion

and operation of the Projects Required in paragraph 6 of this Consent Judgment or required

pursuant to this paragraph 1O.B within the time frames set forth), BRRF shall begin

implementation of the contingency measures upon written notification from MDNR, and

shall complete the projects according to the following schedule. Any of the contingency

projects listed herein may only be triggered at the earliest (and only if an exceedance of the

2008 Lead NAAQS is monitored) after a full three-month calendar period following the

completion and operation ofthe preceding control project1

i. Project B(i) shall be completed within nine (9) months from the date

BRRF receives notification from MDNR to complete the contingency measure.

1 For example, ifproject B(i) is completed and operational on February 15,2016, the next contingency measure could be triggered only ifand after the three month calendar period ofMarch, April and May ofthat year showed an ambient monitored exceedance ofthe 2008 Lead NAAQS. As such, in that scenario the contingency could not be triggered before June 1,2016.

10 11. If in any three-month rolling period after completing and operating project

B(i), the 0.15 llg/m3 rolling three-month average lead standard is exceeded or BRRF

fails to mak:e Reasonable Further Progress, MDNR shall notify BRRF of such

exceedance or failure and BRRF will complete project B(ii) within a timeframe to

be detennined by BRRF and MDNR

iii. If in any three-month rolling average period after completing and

operating projects B(i) and B(ii), the 0.15 llg/m3 rolling three-month average lead

standard is exceeded or BRRF fails to make Reasonable Further Progress, MDNR

shall notify BRRF of such exceedance or failure and project B(iii) shall be

completed within eighteen (18) months of receipt ofthe notice.

IV. If in any three-month rolling average period after completing and

operating proj ects B(i) B(ii), and B(iii), the 0.15 llg/m3 rolling three-month average

lead standard is exceeded or BRRF fails to make Reasonable Further Progress,

MDNR shall notify BRRF of such exceedance or failure and project B(iv) shall be

completed within twelve (12) months of receipt of the notice.

B. Contingency Projects.

L Ventilate reverberatory feed storage building with a minimum design to

achieve negative pressure ofat least .007 inches ofwater column.

11. Projects Technology Study for Fugitive Dust Control. Within a timeframe

to be determined by BRRF and MDNR, BRRF shall submit a work plan to MDNR

for a study of best practices and best available technology for industrial smelter or

metal manufacturing facilities with similar fugitive emissions control challenges.

The work plan is subject to approval by MDNR. The work plan shall provide that

11 the study shall be completed and delivered to MDNR within one hundred and eighty (180) days ofapproval ofthe work plan. The study will list all best practices and best available technologies identified and, for each technology or practice, will identify those technologies and/or practices that BRRF deems technically feasible and cost-effective for inclusion as Contingency Project B(ii), quantify associated emissions reductions, and provide a time frame for implementation of each. Within sixty (60) days of its receipt of the study, MDNR will advise BRRF whether the projects and timelines proposed by BRRF are acceptable and if MDNR agrees that any of the identified technologies or practices are not technically feasible or cost­ effective. Upon approval or after sixty (60) days with no comment, those projects identified in the Study for completion and the deadlines therein shall become a part of this Consent Judgment and fully enforceable hereunder as contingency measures and shall be completed pursuant to the deadlines.

iii. Pave inbound truck parking lot.

iv. Evaluation of ventilation capacity at Main Baghouse. Within a timeframe to be determined by BRRF and MDNR, BRRF shall submit an evaluation of the

Main Baghouse capacity and will identify any projects that are deemed technically feasible and cost-effective to redistribute any excess capacity identified in the evaluation and for inclusion as contingency measures and provide a time frame for implementation. Within sixty (60) days ofits receipt of the evaluation, MDNR will advise BRRF whether the timelines proposed by BRRF are acceptable. Upon approval or after sixty (60) days with no comment, those projects identified by

12 BRRF and the dead1ines therein shall become a part of this Consent Judgment and

fully enforceable hereunder as contingency measures.

C. BRRF shall notifY MDNR within ten (10) business days ofBRRF's completion of

the contingency measures. Within sixty (60) days of such completion, BRRF shaH propose

an additional quantified contingency measure and a proposed timeframe for completion to be

added to this Consent Judgment. Upon approval by MDNR., the additional contingency

measure shall become a part of this Consent Judgment and shall be fully enforceable

hereunder.

Do If BRRF or Doe Run identifies and demonstrates to MDNR's satisfaction

alternative control measure(s) that would achieve attainment with the 2008 Lead NAAQS,

BRRF or Doe Run may substitute the new measure(s) for the contingency measure(s)

identified above, or may change the order of implementation of the contingency measure(s)

and time frames for completion identified above, upon approval of the MDNR's Director of

the Air Pollution Control Program. Any substitute contingency measure shall include a

schedule for completion.

E. Nothing in this agreement shall prevent BRRF from implementing any of these

contingency measures prior to receiving notification from MDNR.

VI. Stipulated Penalties and Force Majeure

11. If the defendants fail to complete construction of the control measures set out in this

Consent Judgment by the dates specified, defendants may be subject to stipulated penalties according to the following schedu1e. The penalties are per day, per violation, and may be assessed by MDNR beginning with the first day of violation after the scheduled deadline date.

Period ofNoncompliance Penalty per Day ofViolation

13 First through 30th day ofnoncompliance $1,000.00

31 st through 60th day ofnoncompliance $2,000.00

61 st through 90th day ofnoncompliance $3,000.00

91 st day ofnoncompliance and beyond $5,000.00

Ifa perfonnance test, conducted per the requirements ofparagraph 8.G. ofthis Consent Judgment, fails to demonstrate compliance with the emission limits stated therein, BRRF may be subject to stipulated penalties according to the following schedule:

First test failure - $1,000

Second test failure - $2,000

Third test failure - $3,000

Fourth (and beyond) test failure - $5,000

If BRRF or Doe Run fails to comply with any other requirements of this Consent Judgment, BRRF or

Doe Run may be subject to stipulated penalties according to the following schedule. The penalties are per day, per violation, and may be assessed by MDNR beginning with the first day of violation after the scheduled deadline date.

Period ofNoncompliance Penalty per Day of Violation

First through 30th day ofnoncompliance $200.00

31 st through 60th day ofnoncompliance $400.00

61 st through 90th day ofnoncompliance $600.00

91st day ofnoncompliance and beyond $800.00

12. Ifany violation is enforceable by more than one agreement or regulatory requirement,

MDNR agrees that it may only seek to enforce either the stipulated penalties discussed in paragraph 11

14 of this Consent Judgment, or the penalty for violation of the specified regulatory requirement, not both, against BRRF and/or Doe Run.

13. All penalties shall be paid within forty-five (45) days of the date of receipt of written notification of the assessment of stipulated penalty from MDNR unless the defendants challenge the penalty pursuant to the dispute resolution procedure outlined in Section VII. If the penalty is challenged, it shall not be paid until thirty (30) days after the Commission's determination that one or both defendants owe the stipulated penalty, and defendants have failed to use, or have exhausted, their rights to review the Commission's decision. If defendants exercise their right to appeal a decision of the

Commission, payment will be due thirty (30) days after a final decision.

14. All penalties shall be paid by check made payable to the State of Missouri (Iron County

Treasurer), and delivered to the Collections Specialist, Attorney General of Missouri, P.O. Box 899,

Jefferson City, Missouri 65102-0899.

15. Upon the request of BRRF or Doe Run, MDNR may in its unreviewable discretion impose a lesser penalty or no penalty at all for violations subject to stipulated penalties. Stipulated penalties are deemed waived if not assessed within two (2) years after MDNR is aware ofa violation.

16. The penalties set forth herein shall not apply in the event ofa force majeure, as defined in this section. For the purposes of this Consent Judgment, force majeure shall be defined as any event arising from causes beyond the control of defendants and of any entity controlled by defendants, which delays or interferes with the performance of any obligation under this Consent Judgment notwithstanding defendants' best efforts to avoid such an event and fulfill the obligation. The requirement that defendants exercise "best efforts to avoid such an event" includes using best efforts to anticipate any potential force majeure event and best efforts to address the effects of any force majeure event (I) as it is occurring, and (2) fol1owing the force majeure event such that the adverse effect or

15 delay is minimized to the greatest extent practicable. Examples of events that are not force majeure

events include, but are not limited to, increased costs or expenses of any work to be performed under this Consent Judgment, changed financial circmnstances, or other financial or budgetary issues. Failure to apply for a required permit or approval, or to provide in a timely manner all information required to obtain a permit or approval necessary to meet the requirements of this Consent Judgment, are not force majeure events.

17. If any event occurs that is likely to delay or interfere with the perfonnance of an obligation under this Consent Judgment, whether or not caused by a force majeure event, defendant shall notify MDNR by telephone within five (5) business days of defendant becoming knowledgeable ofsuch event. Within ten (l0) business days thereafter, defendant shall provide in writing to the State an explanation and description of the reasons for the delay, the anticipated duration ofthe delay; all actions taken or to be taken to prevent or minimize its effects; a schedule for implementation ofany measures to be taken to mitigate the event; and a statement as to whether, in the opinion of defendant, such an event may cause or contribute to the endangerment of pubJic health, public welfare, or the environment.

Defendants shall include with any notice all available documentation supporting the claims that the delay was attributable to a force majeure. Failure to comply with these requirements shall preclude defendant from asserting any claim of force majeure.

18. If the State agrees that the delay or anticipated delay is attributable to a force majeure event, then the State may agree to extend the time for performance of any obligation(s) under this

Consent Judgment that is affected by the force majeure event for the time necessary to complete the obligation(s). The State will notify defendants in writing of the length of the extension, if granted, for performance of the obligation(s) affected by the force majeure event. An extension of the time for

16 perfonnance of the obligation(s) affected by the force majeure event shall not, by itself, extend the time

for performance ofany other obligations.

19. If the State does not agree that a force majeure event has occurred, or does not agree on

the length of any time extension sought by defendant, the issue shall be subject to the dispute resolution

procedures set forth in Section VII. In any such proceeding, to qualify for force majeure defense,

defendant shall have the burden of demonstrating by a preponderance of the evidence that the delay or noncompliance has been or will be caused by a force majeure event, that its duration was or will be

warranted under the circumstances, that defendant exercised or is exercising due diligence by using its best efforts to avoid and mitigate its effects, and that defendant complied with the requirements of paragraph 15-16 above. Should defendant carry the burden set forth in this section, the delay or noncompliance at issue shall be deemed not to be a violation ofthe affected obligation of this Consent

Judgment.

VII. Dispute Resolution

20. Any dispute that arises with respect to the meaning, application or implementation for any provision of this Consent Judgment may be subject to dispute resolution as provided herein, unless the Consent Judgment provision provides that dispute resolution is not available. Any dispute that arises with respect to the meaning, application or implementation of this Consent Judgment shall in the first instance be the subject of infonnal negotiations between defendants and MDNR. Notice of a dispute shall be given by the party alleging the dispute, shall be addressed in writing to the MDNR Director, and copied to the opposing party. Such notice shall state the specific grounds for the dispute, including any supporting documentation and the reliefrequested.

21. The MDNR and defendants shaH have thirty (30) days from the receipt of the notice of the dispute to resolve the dispute. Ifagreement is reached, the resolution shall be reduced to writing and

17 this Consent Judgment modified, if appropriate. If the parties to the dispute are unable to reach

agreement within the thirty-day period and this period is not extended in writing by mutual agreement of

the parties, the matter will be submitted to the Commission. The opposing party may file suggestions in opposition and include any documentation relevant to deciding the dispute. Said suggestions and documentation shall be submitted within fourteen (14) days of submission of the matter to the

Commission. The Commission may hear evidence if needed to reach a decision. The Commission will issue a written decision following its review ofthe record submitted by the parties.

12. The parties will then be entitled to judicial review pursuant to Chapter 536, Revised

Statutes of Missouri. The filing ofa notice ofdispute shall not automatically suspend, extend, postpone, or affect any parties' obligations under this Consent Judgment with respect to the disputed issue unless expressly provided herein or unless the parties agree to the extension, postponement or affect. This provision shall not be construed to prevent either party from requesting a stay of the party's obligations under this Consent Judgment.

VID. Exceptional Events

23. Doe Run or BRRF may provide a demonstration to MDNR that a monitored exceedance at an ambient air monitor was the result of an "exceptional event" as the term is defined at 40 C.F.R.

50.10). IfMDNR agrees that the demonstration supports the characterization of the monitored data as the result of an "exceptional event" as set forth in 40 C.F.R 50.14, MDNR may flag the monitored data to be used as informational purposes only and may submit a demonstration to the Environmental

Protection Agency. Nothing in this paragraph would preclude MDNR from tagging data that was due to an exceptional event and submitting a demonstration to EPA on its own accord or at the request of another party. Any data that is tagged by MDNR to be used for informational purposes cannot be used

18 as a basis to trigger contingency projects. This provision is not subject to Section VII hDispute

Resolution. n

IX. Reservation

24. Nothing in this agreement shall be construed as a waiver of any obligation of defendants or as a permit to defendants under any other environmental laws applicable to defendants.

X. Modifications

25. This Consent Judgment may be modified or amended only by written agreement between the parties, which shall be filed with this Court.

XI. Termination

26. This Consent Judgment and the obligations herein shall terminate upon the payment of any stipulated penalties due and redesignation by the Environmental Protection Agency of the

BuicklVibumum Trend Lead Nonattairunent Area as an attainment area for the 2008 Lead NAAQS. If the SIP revision is not approved by the EPA, the parties may tenninate this Consent Judgment by written agreement.

27. In the event BRRF or Doe Run ceases operation of lead emission units subject to this

Consent Judgment, Doe Run or BRRF shall notify MDNR and will be relieved ofthe injunctive relief or other required practices that were for the purpose ofreducing lead emissions from the subject unit.

XII. Effective Date

28. This Consent Judgment is effective upon entry by the Court.
